LeAnn Rimes finally announced her divorce, but she seems to already have forgotten her soon-to-be ex’s name. An announcement on the singer’s Web site said of her husband, Dean Sheremet, “After much thoughtful mutual consideration, Deane [notice the “e”] and I have agreed to move forward with dissolving our marriage.” Rimes met dancer Dean at the 2001 Academy of Country Music Awards, and after one date, she declared, “This is the guy I want to marry.” Now it seems LeAnn, who’s dating actor Eddie Cibrian, can’t forget him fast enough.
